我想选择一个用户可以通过选项选择的单一问题类别。我已经尝试通过在线找到的资源执行此操作。
类别页面：

@foreach($categories as $category)
            <section>
                <a href="#" class="image">
                    <img src="{{asset('images/pic09.jpg')}}" alt="" data-position="top center" />
                </a>
                <div class="content">
                    <div class="inner">
                        <header class="major">
                            <h3>{{$category->name}}</h3>
                        </header>
                        <p></p>
                        <ul class="actions">
                            <li><a href="/test/{{$category->id}}" class="button">Learn more</a></li>
                        </ul>
                    </div>
                </div>
            </section>
        @endforeach

这是我正在使用的TestController，显示控制器可能会随机选择带有category_id的问题和选项：

namespace App\Http\Controllers;

use App\Category;
use App\Http\Requests\StoreTestRequest;
use App\Option;

class TestsController extends Controller
{
    public function show($id)
    {
        $categories = Category::find($id)->with(
            ['categoryQuestions' => function ($query) {
                $query->inRandomOrder()
                    ->with(
                        ['questionOptions' => function ($query) {
                            $query->inRandomOrder();
                        }]
                    );
            }]
        )
            ->whereHas('categoryQuestions')
            ->get();

        return view('client.test', compact('categories'));
    }
    
    public function store(StoreTestRequest $request)
    {
        $options = Option::find(array_values($request->input('questions')));

        $result = auth()->user()->userResults()->create(
            [
            'total_points' => $options->sum('points')
            ]
        );

        $questions = $options->mapWithKeys(
            function ($option) {
                return [$option->question_id => [
                        'option_id' => $option->id,
                        'points' => $option->points
                    ]
                ];
            }
        )->toArray();

        $result->questions()->sync($questions);

        return redirect()->route('client.results.show', $result->id);
    }
}

web.php

// User
Route::group(['as' => 'client.', 'middleware' => ['auth']], function () {
    Route::get('home', 'HomeController@redirect');
    Route::get('dashboard', 'HomeController@index')->name('home');
    Route::resource('/test', 'TestsController');
    Route::get('results/{result_id}', 'ResultsController@show')->name('results.show');
    Route::get('send/{result_id}', 'ResultsController@send')->name('results.send');
});

这是我正在使用的资源中的Blade文件：

@extends('layouts.home')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">

                            </div>
                        </div>
                    @endif

如何让Testcontroller从单个类别中选择问题和答案，并保存用户答案的结果？
